Currently ReviewBoard has a limited way of rendering SVG files and does 

not allow for proper scaling and zooming. We are now attempting to utilize 

SVG potential to full extent and allow users to inifinitely scale/zoom SVG images.
The new solution utilizes viewBox attribute of SVGs and attempts to manipulate it

in order to create zoom-in ability and ability to span SVG. Moreover, the solution

also dynamically rescales and adjusts comment boxes based on the viewBox.
Currently, the new features only apply to a single image, i.e. no diffs view.

The diff view with SVGs will behave the same way as with the bitmap images.

However, there is no ability to zoom in/out or span the SVG.

The UI was tested using Google Chrome and Safari.
Unit tests were but no additional tests were added.
